Engineering Contradiction Analysis
1Productivity
If statistical probability calculations are performed using classical computing devices, then computational accuracy is maintained, but execution time and energy consumption increase significantly
Solution Approach 1:
The patent replaces classical computational systems with a thermodynamic system that uses physical oscillators to perform statistical sampling. The oscillators naturally exhibit thermal fluctuations that directly represent statistical distributions, eliminating the need for computational algorithms to calculate these statistics. This substitution of mechanical computation with physical thermodynamic processes resolves the contradiction by achieving both speed (through direct physical measurement) and energy efficiency (through natural thermal processes).
Solution Approach 2:
The patent changes the fundamental parameter representation from digital computational states to continuous physical oscillator states governed by thermodynamic parameters. By mapping statistical variables to physical oscillator amplitudes and frequencies, the system directly measures statistical properties through thermal equilibrium rather than computational iteration, thereby improving execution speed while reducing energy consumption through efficient thermodynamic processes.
2Measurement precision
If complex statistical computations are performed using classical computing devices, then accurate results are obtained, but calculation time increases
Solution Approach 1:
The patent substitutes computational algorithms with physical thermodynamic processes. The oscillators' natural thermal fluctuations directly embody statistical distributions, allowing measurement of statistical properties through physical observation rather than computational calculation. This maintains accuracy by directly representing statistical mechanics principles while dramatically reducing calculation time through parallel physical processes.
Solution Approach 2:
The thermodynamic system continuously samples statistical properties through ongoing thermal fluctuations of the oscillators. Rather than performing discrete computational steps, the system maintains continuous thermal equilibrium that naturally provides statistical samples, eliminating idle computational time and achieving both high accuracy and fast execution through uninterrupted physical processes.

AI summary
A thermodynamic computing chip that is configured to perform designated portions of an algorithm is disclosed. In some embodiments, algorithms executing on classical or other types of computing devices may delegate tasks, such as Monte Carlo sampling methods, to a thermodynamic chip, wherein the thermodynamic chip directly performs the Monte Carlo sampling methods by sampling physical elements of the thermodynamic chip, as the physical elements evolve according to Langevin dynamics. In some embodiments, the physical elements of the thermodynamic chip are configured using magnetic couplings to implement an engineered Hamiltonian. Also, in some embodiments, the thermodynamic chip may be sampled and weights and biases in the engineered Hamiltonian may be learned in order to model a particular phenomenon, such as Langevin dynamics of a particular system.
